Abstract
An approach is provided for fault detection and notification for a composite transport group (CTG). A component link of a CTG associated with a label switched path (LSP) is monitored. A fault is detected in the component link. It is determined whether traffic of the LSP can be transparently rerouted to another component link of the CTG based on resource availability of the other component link. The traffic is transparently rerouted to the other component link if resources are available. An upstream label switched node is notified if resources are unavailable.
